Abstract (en)

[origin: WO9204928A2] The present invention provides an inhaler device (1) for inhaling an aerosol in a desired dosage, comprising a housing (2) in which is received a reservoir (3) of powder or liquid, an inhaling piece (7) placed on the housing and means for transporting the powder or liquid from the reservoir to the inhaling piece in a dosage required for the aerosol. The transporting mechanism can be a spring loaded plunger (11) with a toroidal space along its walls, that is filled by the medication when the plunger is pushed down, and that brings the medication into a whirl mixing chamber (16, 55), when it is pushed upwards by the spring. In another embodiment the transport mechanism can be a worm (56), hand rotated, in order to transport medication from the reservoir into the whirl mixing chamber (16, 55). The whirl mixing chamber (55), activated by the patient's inhaling, has two feed channels (62-63), one to transport the medication into the chamber, the other to cross the first one at right angles to disrupt the flow and enhance medication mixing.
